LARAVEL Professional Standards & Competencies 4 — Questions and Answers
Question 1: What is the professional Laravel convention for naming database tables created by Eloquent models?
- PascalCase singular matching the model name
- snake_case plural of the model name (Correct answer)
- camelCase plural of the model name
- UPPERCASE singular of the model name
Correct answer: snake_case plural of the model name
By convention, Eloquent maps a model named `UserProfile` to a table named `user_profiles` using snake_case plural form.
Question 2: Which practice best demonstrates professional use of Laravel's dependency injection container?
- Calling `app()->make()` everywhere in business logic
- Type-hinting dependencies in constructor or method signatures (Correct answer)
- Using global helper functions to resolve all dependencies
- Storing service instances in global variables
Correct answer: Type-hinting dependencies in constructor or method signatures
Type-hinting dependencies allows Laravel's IoC container to automatically resolve and inject them, making code testable and loosely coupled.
Question 3: What is the purpose of Laravel Horizon in a professional application?
- It provides a web-based UI for managing and monitoring Redis-backed queues (Correct answer)
- It is a caching layer for Eloquent models
- It schedules artisan commands on a cron
- It manages API rate limiting
Correct answer: It provides a web-based UI for managing and monitoring Redis-backed queues
Laravel Horizon provides a real-time dashboard and configuration for monitoring Redis queue workers, job throughput, and failures.
Question 4: In professional Laravel API development, what HTTP status code should be returned when a resource is successfully created?
- 200 OK
- 201 Created (Correct answer)
- 204 No Content
- 202 Accepted
Correct answer: 201 Created
HTTP 201 Created is the semantically correct response for a successful POST request that creates a new resource.
Question 5: Which Laravel feature allows professionals to version their API routes cleanly?
- Using query parameters like `?version=v1`
- Grouping routes with a URI prefix like `api/v1` using Route::prefix() (Correct answer)
- Creating separate Laravel installations per version
- Using middleware to rewrite URLs
Correct answer: Grouping routes with a URI prefix like `api/v1` using Route::prefix()
Route::prefix('v1') groups all v1 API routes under the `/api/v1` URI namespace cleanly within `routes/api.php`.
Question 6: What is the professional Laravel approach for transforming Eloquent model data before returning it in an API response?
- Manually build arrays in the controller
- Use API Resource classes (`php artisan make:resource`) (Correct answer)
- Return the Eloquent model directly with `->toJson()`
- Use Blade templates to format JSON output
Correct answer: Use API Resource classes (`php artisan make:resource`)
API Resource classes provide a transformation layer that controls exactly which model attributes and relationships are exposed in API responses.
Question 7: Which professional practice should be followed when writing Laravel migrations to ensure they are safely reversible?
- Only implement the `up()` method
- Implement both `up()` and `down()` methods correctly (Correct answer)
- Use raw SQL in both methods without Schema builder
- Always drop and recreate tables in `down()`
Correct answer: Implement both `up()` and `down()` methods correctly
Properly implementing `down()` as the inverse of `up()` ensures migrations can be rolled back cleanly during development and deployments.
